Before you buy — quick checklist

  • Confirm your existing pump label reads 230V — this pump is not dual voltage
  • Match the HP rating on your old pump nameplate to 3.5 HP before ordering
  • Verify your spa control system supports a two-speed pump on the same circuit
  • Check your spa's plumbing union size and thread configuration before disconnecting the old pump
  • Confirm your electrical supply can support 11.0A high-speed draw on a dedicated 230V circuit
  • Note your existing pump's frame size — this is a 56Y frame and must match your motor mounting bracket

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
